90 Camaro

[90CamaroRS]

I Have a 1990 Camaro RS 305, Ive put Flowmasters on it, rebuilt the trans w/ a shift kit, also i run a K&N filter in it. I was thinks about adding a performance camshaft/lifter kit. Also the idea of removing the cat, and giving it posi has risen. Any ideas on what to do about this motor as in performance? Any suggestions, ideas, any knowledge on what i can do to get more HP, im open to learn and listen to all. Thanks All!

Ditch that 305. Its a roach. I had one. You can throw that cam in there and still lose to stock 5.0s

Hey Kevin, for some reason I knew it was you. Its the kid with the red Camaro from school. a Cam and Lifters should help out nicely, but if your gonna go fast, I'd put a 350 in there.

ditch the 305 they are only good for one thing boat anchers.just start saving for a 350.plus u should ditch the fuel injection.some people like the shit but i think carbs are alot easier to work with and on.

[Pennywise]

i hate to say it but i agree with eveyone else,a 350 is the way to go...i have a 83 Z28 and i put a 350 in mine and its like night and day..it would be well worth it!!

[martz0r]

305 ftl. ditch that mo fugga and get a 350 in there! youre gonna make more hp with a stock 350 than a 305 with money dumped in

[90CamaroRS]

How much for a 350 do you think it'll cost me and how much stuff am i gona have to change to make the car run with the 350?

[-campy-]

dude keep the 305 put 350 heads on it forged internals go multiport fuel injection and spray that bitch all for the same price of droping the 350 in it you can put a cam lifters and your car will go

[Suicidal Racing]

if your running a 305 right now.just yank it out and drop the 350 in.the blocks are the exact same size.now it is do u want it to use a carb or be fuel injected.if i where u i would go carb.more choice with intakes and carb size to go with.the tpi intake runners are good at making tq but after u get up to 5k it doesn't make shit for hp.plus u will get rid of wireing and other pointless b.s that gm put on the cars.

This is the worst advice I have ever heard....

Forged internals on a 305?? :lol:

Yall have to remember that this is probably a high school kid. Dropping a 350 in isnt cheap and hes just looking for some performance. Is it going to be the fastest thing on the road, no, but it might be good for him.

You can do the simple bolt ons. Headers, cold air intake, chip, lower t-stat, etc. The TBI sucks though. You can actually get a new intake that is supposed to help a bit from Edelbrock. A cam will help out too. Ditch the cats, actually, you can just hallow them out. Its free.

[corey r.]

I did most of the bolt ons to my 305. I still wasnt happy with it! I wished I had listened to my elders and saved my money.

Kinda like modding a V6, but everyone learns on thier own I guess!

[90CamaroRS]

Yea i ain't got too much money and im a senior in highschool.. so im guess im kinda looking for a good bang for my buck as they say..

[EliteZ]

well bang for your buck.. depending on whats good for a 350 short block is 150ish to 900. I am really sure your 305 stuff will work fine. Though that would be stupid. So maybe save up for a shortblock, heads, and a cam 350 style.

Yeah, a 350 swap is a more logical choice, but then hes got to buy a whole new intake setup because you cant use the TBI on the 350 so add in about 500 for a used TPI setup, then youll need the whole engine harness for it, etc... It adds up fast. Before you know it, your a couple grand into it.

You "could" get a used 350 TPI motor with a harness, computer and such to swap, but its still more money than you probably have. Its also a lot of work to switch it all out and Im sure this is your only car. I know where youre coming from as I had a 92 RS in HS.

He'd have to get a 85+ 350 so he could TPI it. Carb is too much of a headache to deal with. Then you have the problem of how much its been abused. It may blow up a week after he installs it.

[EliteZ]

All you guys know what your talking about. And thats cool. But how come 'everyone' can't agree?
Some guys GO CARB is so easy

Others CARB is so hard stay Computer controlled(EFI, TPI, TBI, MFI, etc)

A carburator is a mechanical device. You just change jet sizes, powervalves and squirters, which isnt hard. Just trial and error. (Holley carbs here).

the Electronic stuff, requires moderate to excellent computer knowledge(to do it yourself), have a laptop, and software to tune your mods on your car. that seems alot more confusing to me, even though it give you more handle on whats going on.

[Suicidal Racing]

i'm right there with u.i'll take a carb any day shit i always had people adj my carb or rebuild it for me.tell like 2 years ago when i only had enough money for the rebuild kit.so guess what i did.yep i sat my ass down turned the classic rock on and rebuilt that son of a bitch it really wasn't hard at all.besides getting high from the 114 octane race gas that i had sitting in the bowls still.it was really a good learning experiance

[Country Boy]

Carbs are simple, yes, but you will make more power with EFI, also better gas milage. With EFI, you wont have to readjust everytime the temp changes 10*s ;) Carbs are also simpler, but is it worth it, to me, no.

[90CamaroRS]

Woo Hoo Got My Camaro To Fit In My Avatar Woot Now Yall Can See My Beast Lol :lmao:

[SteveIGuess]

i have a built 86 camaro, if you patiently save up you will hand many their asses in time my friend....
but ya make sure you put subframes on it before you start making power, otherwise the unibody becomes a pretzel.

I say stick with the 305 till you get out of school and have a good job going so you can aford to do a 350 right the first time. If you want, you can still do bolt ons that will work with the 305 and still work on the 350 when you do swap. But go here (www.thirdgen.org) and read up on stuff you can do to it. If I remember right there was a guy with a 92 z28 with the 305 tpi motor running 13's or 12's. So the 305 is not all that bad. You just have to work with what you got. Adam :-)

thanks man!

Pretty much what I was doing until I got sick of buying gas twice a week for my Camaro. Since you have the 305TBI stock it puts out 175 and 255lbtq. My plan was to go out and buy a 350 setup from a Z28/Vette and mate it to my 5 speed. But with the gas thing and all I'm selling the Camaro so I could buy something a little more economical even though I get 18mpg city!!!
